This invention aims to provide functionally and structurally improvedarticles, primarily intended for use in connection with the manufactureof shoes, and also aims to teach a novel l'5 method of manufacture inconnection, with thel production of shoes.

It is an object of the invention to provide a sole of novelconstruction, and by means of which the methods of manufacturing shoesmay be yl greatly improved.

A further object is that of providing an inset or iiller piece inconnection with the use of insoles and by means of ,which the resultantproduct will be greatly improved.

l A still further object is that ofteaching a method of manufacturingshoes, which method will preferably employ soles and ller pieces asafore noted, the practice of such method resulting in the expeditiousmanufacture of shoes having improved characteristics.

- Moreover, by means of the present invention, there are provided solesand insets which may be economically manufactured in large quantities,and the method as taught by the present invention will not require theservices of an especially skilled workman.

With these and other objects in mind, reference is had to the attachedsheet of drawings illustrating practical embodiments of the invention,and in which:

Fig." 1 is a perspective View of an inner sole;

Fig. 2 is a transverse sectional view taken along the lines 2--2 and inthe direction of the arrows as indicated in Fig; 1;

Fig. 3 is a perspective view of a shoe-upper and showing the same inassociation with a sole of the type illustrated in Fig. 1, during thelasting operation;

Fig. 4 is a view similar to Fig. 3, but showing the shoe after the samehas been subjected to a further step of manufacture;

Fig. 5 is a transverse sectional view of the shoe and sole asillustrated in Fig. 4, with an outsole added;

Fig. 6 isV a sectional and perspective Aview (cl. iz-uz) by leavinguncut or unscored zones Il, and deliberate destruction oi which is, ofcourse, necessary to eiect removal 'of the portion I2.'

In forming the slit or score Il, care is preferably taken so that theedges shall be beveled as- 5' at Il in Fig. 2. It is obvious that thisbeveling might be followed to any desired extent, and might readily beconducted at the time the sole is stamped or cutout.

In any event, the inner sole l0 and the upper I0l I5 may be `applied inthe usual manner to the last I6, and the lasting operation is conductedin any suitable manner, as, for example, by cementing the lastingallowance I1 to the margins I8 of th'e insole. During this operation,andincident to 15 the central portion l2, the insole will oifer suiilicient-resistance to buckling so -that no dilculties may be apprehended.Thereafter, by simply cutting through the zones I3, the central portionmay be removed. 20

The operator may now apply to the insole the iiller piece I9, whichpiece should be of a thickness such that it will extend from the planeof the inner face of the sole l 0 to the plane of the outer face of. thelasting allowance. While, for the 25 purpose of illustration, the fillerpiece has been shown as having a somewhat reduced area', it will ofcourse, be understood that preferably the area thereof should besubstantially equal to the area between the inner edges of the lastingal- 30 lowance so that substantially continuous surfaces are provided. v

Of course, before the application of the illler piece I9, but after theremoval of the central portion l2, the operator may modify the, edges of35 the central opening as may seem most desirable. Such modification maytake the form of beveling to a greater extent than has been done prior'tol the application of the inner sole to the upper. Alsoas shown, inFig. 7, the filler piece need not i0 necessarily have those edges whichcontact the edges of the central sole beveled, but instead a shoulder2li may be provided at this point, the

n depth of the shoulder being such that the inner cementing be resortedto to assure a permanent union between these parts. In many respects itis preferable that slitting, as indicated at il, be resorted to, but itis obvious that, regardless of whether a composition or other sole isbeing utilized, a line of weakening might be furnished, as, for example,by a crushing action, which would substantially remove said portion butnevertheless leave in existence a thin layer of material, precludingaccidental detachment of such portion. Under the latter circumstancesthe unsevered areas i3 might be utilized or entirely dispensed with, inthat the operator could very easily complete the removal of the centralportion. In certain instances, and especially where scoring is utilized,these unsevered areas mightagain be dispensed with.

From the foregoing it is obvious that a sole is provided and a methodtaught which will permit of adequate support being furnished during thelasting operation and by means of which, after such operation has beencompleted, the rigidifying portion may be removed with facility andreplaced by a filler piece or inset which will assure the incorporationof maximum flexibility and comfort in the resulting shoe. The outerfaces of the lasting allowance and inset might be skived, so that theouter sole might readily be cemented thereto, it being, however,immaterial-in so far as the present invention is concerned-whethercementing, stitching, or other forms of attachment are employed.

It will be noted, particularly in Figs. 5 and 7, that by virtue of thethickened insert in the inner sole the latter hasa centrally elevatedportion or landwhich projects outwardly from the bottom face "of thelasted upper. The boundary of this landed portion approximatelycoincides with the inner boundary of the inner sole lasting allowance,and in the complete lasted upper assembly there is a` substantially evensurface extending from side to side of the shoe which is adapted tomatefirmly and snugly with an outer sole, which latter may be readilymanufactured in a flat condition with a minimum number of preformingsteps.

From the foregoing,l it will be obvious that, among others, the severalobjects of the invention as specifically afore noted, are achieved. Itwill be appreciated that numerous changes in construction might beresorted to, and that the steps and the method might be varied in manyrespects without departing from the spirit of the invention as dened bythe claims.

Having thus described the invention, what is claimed as new and desir`edto be protected by Letters Patent is: Y
